摘要:
A data processing apparatus edits an actual data portion excluding a header from data transmitted by streaming transmission from a first information processing apparatus after start of streaming transmission. The data processing apparatus transmits edited actual data portion and header to a second information processing apparatus by streaming transmission. The second information processing apparatus reproduces the voice data or the animation data transmitted by streaming transmission. The actual data portion is edited so that the voice data or the animation data to be transmitted may be reproducible in the second information processing apparatus, and so that a program may become unexecutable even if it would be transmitted to the second information processing apparatus. Even if the voice data or the animation data transmitted from the first information processing apparatus by streaming transmission would be deteriorated, an executable virus program does not transmitted to the second information processing apparatus, thereby that makes it possible to realize the streaming transmission method which can realize simple and high security.
摘要:
The present invention provides a communication assistance process that is performed by a communication assistance device connected to a plurality of user terminals via a network. During a communication (or video) conference call, when assistance data associated with a topic in the conference is provided to a plurality of user terminals in the form of a voice data, the communication assistance process adjusts the sound volume of voice data in the assistance data if it was determined that voice data is included in the communication data received from the plurality of user terminals, and if voice data is also included in the assistance data, the assistance data that includes sound volume adjusted voice data is then provided to the plurality of user terminals. Accordingly, the communication assistance process allows communications in a conference system to proceed smoothly.
